Installation Help

To make this possible Half-Life: ReSrced runs on the open-source Xash3D FWGS engine. While it's not as plug-and-play as a regular mod for the Steam version of Half-Life, I have made a step-by-step installation instruction that will make the process quite easy. I recommend everyone use it.
